“Rich Ferraro from @glaad informs me that c’sucker is an anti-gay epithet. In which case I apologize and will retire it from my vocabulary,” Baldwin wrote Thursday night.

Baldwin came under fire on Thursday after TMZ posted video of the actor in which he seemed to call a paparazzo a “c—sucking f-g.” The “30 Rock” star subsequently took to Twitter to clarify that he’d called the photographer a “fathead.”

“Wow, Alec Baldwin shows his true colors yet again,” Cooper wrote early Friday. “How is he going to lie and excuse his anti-gay slurs this time?”

Cooper later added, “Just read Alec Baldwin‘s latest excuses. They are actually so ridiculous they are funny.”

In June, Baldwin issued an apology to GLAAD after calling Daily Mail reporter George Stark a “queen” and threatening to beat him. Stark had accused Baldwin’s wife Hilaria of tweeting during the funeral service for “Sopranos” actor James Gandolfini.
